Abstract
Disclosed is an electrochromic display device including a display substrate, a display electrode provided on the display substrate, a first electrochromic layer provided on the display electrode, an intermediate display electrode provided above the first electrochromic layer separately from the first electrochromic layer, a second electrochromic layer provided on and contacting the intermediate display electrode, an opposed substrate, an opposed electrode provided on the opposed substrate, and an electrolyte solution provided between a surface of the display substrate on which the display electrode is formed and a surface of the opposed substrate on which the opposed electrode is formed, wherein the intermediate display electrode contains a rod-shaped, whisker-shaped, or long-fiber-shaped electrically conductive fine particle, and at least a portion of a space in the electrically conductive fine particle is filled with a material forming the second electrochromic layer.
